Drinking water in Estenfeld

5 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.

How to read the share of the parametric value

12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.
< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.

Several samples per year: for chemical parameters the mean value is given, for microbiological ones the highest measured value. There the parametric value is zero — a single finding would disappear in the average, and it is precisely that finding which is the information. Which reference applies is stated in the last column of the table.

Assigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.

These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 09/12/2019. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.

Frequently asked questions about drinking water in Estenfeld

How much nitrate is in the drinking water in Estenfeld?
Zweckverband zur Wasserversorgung Mühlhausener Gruppe publishes a nitrate value of 26,3 mg/l for the supply zone Hochbehälter Grombühl 2. The statutory parametric value is 50 mg/l; the measured value represents 53 % of the parametric value. Basis: Publication by the water supplier, retrieved on 08/08/2026.
Who supplies the drinking water in Estenfeld?
Zweckverband zur Wasserversorgung Mühlhausener Gruppe. The values shown here come from the supply zone Hochbehälter Grombühl 2 and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.

General questions — how current the data is, limit of quantification, parametric values, who is behind this site — are answered under Questions & answers.
